Fix radare2-cutter: Wrap Cutter with Qt wrapper

[esclear]

Fix an issue preventing Cutter from starting because it can't find Qt plugins.

Motivation for this change

When using the current version of radare2-cutter, I encountered the following error message when starting Cutter:
qt.qpa.plugin: Could not find the Qt platform plugin "xcb" in "".

The problem was fixed as proposed in #54525 by wrapping Cutter with the Qt application wrapper.
